Codeofchina.com is in charge of this English translation. In case of any doubt about the English translation, the Chinese original shall be considered authoritative. The Electromagnetic compatibility - Generic standards series currently consist of the following parts: ——GB/T 17799.1-2017 Electromagnetic compatibility - Generic standards - Immunity for residential, commercial and light-industrial environments ——GB/T 17799.2-2003 Electromagnetic compatibility - Generic standards - Immunity for industrial environments ——GB 17799.3-2012 Electromagnetic compatibility (EMC) - Generic standards - Emission standard for residential, commercial and light-industrial environments ——GB 17799.4-2012 Electromagnetic compatibility (EMC) - Generic standards - Emission standard for industrial environments ——GB/T 17799.5-2012 Electromagnetic compatibility (MEC) - Generic standards - HEMP immunity for indoor equipment This is part 1 of GB/T 17799. This part is developed in accordance with the rules given in GB/T 1.1-2009. This part replaces GB/T 17799.1-1999 Electromagnetic compatibility - Generic Standards - Immunity for residential, commercial and light-industrial environments. The following main changes have been made with respect to GB/T 17799.1-1999: ——The Clause 4 "Description of locations" in previous standard is deleted, with the contents in it combined into Clause 1 of this standard; ——Four terms, namely, "signal port", "power port", "long distance lines" and "low voltage" are added to Clause 3 “Terms and definitions”, and the term "functional earth port" in Clause 3 of previous standard is deleted; ——In “Table 1 Immunity - Enclosure port” of Clause 8 of this standard, the "Radio-frequency electromagnetic field - Keyed carrier” in Table 1 of Clause 9 of the previous standard is deleted, and the “Radio-frequency electromagnetic field - Amplitude modulated” with a test specification of 1.4 GHz~2.7 GHz is added; ——In “Table 1 Immunity - Enclosure port” of Clause 8 of this standard, the test specification “60 Hz” in “1.1 Power-frequency magnetic field” of Clause 9 of previous standard is deleted; and the test specifications and units of “4.2 Voltage dips” and “4.3 Voltage interruptions” in “Table 4 Immunity - Input and output AC power ports” are adjusted; This part is modified in relation to the international standard IEC 61000-6-1: 2005 Electromagnetic compatibility (EMC) - Part 6-1: Generic standards - Immunity for residential, commercial and light-industrial environments. The technical differences between this part and IEC 61000-6-1: 2005 and their causes are as follows: ——As for the normative references, technical adjustments have been made in this part to adapt to the technical conditions of China, which are mainly reflected in Clause 2 "Normative references", with the corresponding international standards replaced with national standards equivalent to them; and GB/T 2900.83 Electrotechnical terminology - Electrical and magnetic devices is added; ——In Clause 8, the test specification "60 Hz" in the previous standard is deleted from 1.1 of “Table 1 Immunity - Enclosure port”; and the "30 cycles" in "4.2 Voltage dips” and "300 cycles” in "4.3 Voltage interruptions" of "Table 4 Immunity - Input and output AC power ports” are deleted. As 60 Hz is not adopted in the power frequency magnetic field immunity test in China, relevant parameters related to 60 Hz are deleted from this part. The following editorial changes have also been made in this part: ——The name of this part is changed to Electromagnetic compatibility - Generic standards - Immunity for residential, commercial and light-industrial environments. This part was proposed by and is under the jurisdiction of SAC/TC 246 the National Technical Committee on Electromagnetic Compatibility of Standardization Administration of China. The previous edition replaced by this part is as follows: ——GB/T 17799.1-1999. Electromagnetic compatibility - Generic standards - Immunity for residential, commercial and light-industrial environments 1 Scope This part of GB/T 17799 for EMC immunity requirements applies to electrical and electronic equipment intended for use in residential, commercial and light-industrial environments. Immunity requirements in the frequency range 0 Hz to 400 GHz are covered. No tests need to be performed at frequencies where no requirements are specified. This generic EMC immunity standard is applicable if no relevant dedicated product or product-family EMC immunity standard exists. This part applies to equipment intended to be directly connected to a low-voltage public mains network or connected to a dedicated DC source which is intended to interface between the equipment and the low-voltage public mains network. This part applies also to equipment which is battery operated or is powered by a non-public, but non-industrial, low-voltage power distribution system if this equipment is intended to be used in the locations described below. The environments encompassed by this part are residential, commercial and light-industrial locations, both indoor and outdoor. The following list, although not comprehensive, gives an indication of locations which are included: ——residential properties, for example houses, apartments; ——retail outlets, for example shops, supermarkets; ——business premises, for example offices, banks; ——areas of public entertainment, for example cinemas, public bars, dance halls; ——outdoor locations, for example petrol stations, car parks, amusement and sports centres; ——light-industrial locations, for example workshops, laboratories, service centres. Locations which are characterised by being supplied directly at low voltage from the public mains network are considered to be residential, commercial or light-industrial. The object of this part is to define the immunity test requirements for equipment specified in the scope in relation to continuous and transient, conducted and radiated disturbances including electrostatic discharges. The immunity requirements have been selected in this part to ensure an adequate level of immunity for equipment at residential, commercial and light-industrial locations. The levels do not, however, cover extreme cases, which may occur at any location, but with an extremely low probability of occurrence. Not all disturbance phenomena have been included for testing purposes in this part but only those considered as relevant for the equipment covered by this part. These test requirements represent essential electromagnetic compatibility immunity requirements. Notes: 1 Information on other disturbance phenomena is given in IEC 61000-4-1 [1]. Test requirements are specified for each port considered. 2 Safety considerations are not covered by this part. 3 In special cases, situations will arise where the levels of disturbances may exceed the test levels specified in this part; for example where a hand-held transmitter is used in proximity to an equipment. In these instances, special mitigation measures may have to be employed. 2 Normative references The following referenced documents are indispensable for the application of this document.

If, as a result of the application of the tests defined in this part, the equipment becomes dangerous or unsafe, the equipment shall be deemed to have failed the test. A functional description and a definition of performance criteria, during or as a consequence of the test, shall be provided by the manufacturer and noted in the test report, based on one of the following criteria for each test as specified in Tables 1 to 4. a) Performance criterion A The equipment shall continue to operate as intended during and after the test. No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer, when the equipment is used as intended. The performance level may be replaced by a permissible loss of performance. If the minimum performance level or the permissible performance loss is not specified by the manufacturer, either of these may be derived from the product description and documentation and what the user may reasonably expect from the equipment if used as intended. b) Performance criterion B The equipment shall continue to operate as intended after the test. No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer, when the equipment is used as intended. The performance level may be replaced by a permissible loss of performance. During the test, degradation of performance is however allowed. No change of actual operating state or stored data is allowed. If the minimum performance level or the permissible performance loss is not specified by the manufacturer, either of these may be derived from the product description and documentation and what the user may reasonably expect from the equipment if used as intended. c) Performance criterion C Temporary loss of function is allowed, provided the function is self-recoverable or can be restored by the operation of the controls. 5 Conditions during test The equipment under test (EUT) shall be tested in the expected most susceptible operating mode e.g. identified by performing limited pre-tests. This mode shall be consistent with normal applications. The configuration of the test sample shall be varied to achieve maximum susceptibility consistent with typical applications and installation practice. If the equipment is part of a system, or can be connected to auxiliary equipment, the equipment shall be tested while connected to the minimum representative auxiliary equipment necessary to exercise the ports in a similar manner to that described in GB/T 9254. In cases where a manufacturer's specification requires external protection devices or measures which are clearly specified in the user's manual, the test requirements of this standard shall be applied with the external protection devices or measures in place. The configuration and mode of operation during the tests shall be precisely noted in the test report. It is not always possible to test every function of the equipment; in such cases the most critical mode(s) of operation shall be selected. If the equipment has a large number of similar ports or ports with many similar connections, a sufficient number shall be selected to simulate actual operating conditions and to ensure that all the different types of termination are covered. The tests shall be carried out within ranges of temperature, humidity and atmospheric pressure specified for the product and at the rated supply voltage, unless otherwise indicated in the basic standard.

在试验期间和试验之后，设备应按预定方式连续工作。当设备按预定方式工作时，性能降低程度或功能丧失不允许低于制造商规定的性能水平。性能水平可以用允许的性能丧失替代。如果制造商没有规定最低性能水平或允许丧失的性能，则二者均可从产品说明书和产品文件中得到，或者在设备按预定的方式使用时，从用户的合理期望中得出。 b)性能判据B 在试验之后，设备应按预定方式连续工作。当设备按预定方式使用时，性能水平降低或功能丧失不允许低于制造商规定的性能水平。性能水平可以用允许的性能丧失来替代。在试验期间，允许性能水平降低，但实际工作状态或存储的数据不允许改变。如果制造商没有规定最低性能水平或允许丧失的性能，则二者均可以从产品说明书和产品文件中得到，或者在设备按预定的方式使用时，从用户的合理期望中得出。 c)性能判据C 允许暂时丧失功能，只要这种功能可自行恢复或者可以通过操作控制器来恢复。 5试验条件 受试设备应在预期的最敏感工作模式(例如：由有限的预测试确定)下进行试验。这种工作状态应符合正常的使用情况。应变化试验样品的配置以便获得在典型应用和实际安装中量大的敏感度。 如果设备是系统的一部分，或者可以连接辅助设备，则设备在进行试验时应连接数量最少且有代表性的必须使用端口的辅助设备，类似的描述见GB/T 9254。 如果制造商的技术规范特别要求外部保护装置或措施，并已在用户使用手册中明确作出规定，则在应用本部分的试验要求时要有适当的外部保护装置或措施。 试验期间的试验布置和工况都应准确地记录在试验报告中，当不能对设备的每一项功能都进行试验时，应选择最关键的工况来试验。 如果设备有许多类似的端口或某些端口有许多类似的连接，那么应选择足够数量的端口来模拟实际工作状态以保证涉及所有不同类型的终端。 应在产品规定的温度、湿度和气压范围内，以额定电源电压进行试验，除非基础标准另有规定。 6产品文件 如果制造商要求按本部分在试验期间或试验之后，使用其自身的技术规范来评定产品的EMC性能合格水平或性能水平降低情况，则应在用户文件中说明。在需要时，制造商应能提供这种技术规范。 7适用性 抗扰度试验的应用取决于具体的设备及设备的配置、端口、技术、工艺和工作状态。 应根据表1～表4的要求，对设备的有关端口进行试验，并应仅在有关端口存在时进行试验。 可以根据具体设备的电气特性和用途来确定哪些试验是不适当的和不必要的，在这种情况下，应在试验报告中记录不试验的理由。 8抗扰度试验要求 本部分涉及的设备抗扰度试验要求是基于端口给出的。 试验应以完全确定的和可重复的方式进行。 试验应以单个的试验依次逐项进行，试验顺序是任意的。 有关试验、对应的试验发生器、适用的方法和试验布置的描述见下列各表中列出的基础标准。 这些基础标准的内容在此不赘述，但在试验实际应用时需要的修改或补充信息仍在本部分中给出(见表中的“注释”和“注”)。 表1外壳端口抗扰度试验 序号 环境现象 试验规范值 单位 基础标准 注释 性能判据 1.1 工频磁场 50 3 Hz A/m GB/T 17626.8 — Aa 1.2 射频电磁场，调幅 80～1
